Given numbers are 640, 360, 830, 218

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(640, 360) = 5760

GCD(640, 360) = ( 640 x 360 ) / 5760

= 640 / 360

= 640

Step2:

LCM(40, 830) = 3320

GCD(40, 830) = ( 40 x 830 ) / 3320

= 40 / 830

= 40

Step3:

LCM(10, 218) = 1090

GCD(10, 218) = ( 10 x 218 ) / 1090

= 10 / 218

= 10

So, Greatest Common Divisor of 640, 360, 830, 218 is 2
